在自闭症谱系障碍（ASD）患者中，已经发现了执行能力（如认知灵活性）的障碍。然而，目前尚不清楚这些人是否也会在另一种执行能力方面出现障碍：抑制控制。在本研究中，我们对18名ASD儿童，23名ASD儿童的兄弟姐妹和25名典型发育儿童进行了三项抑制任务。在控制了年龄、整体智商和处理速度的个体差异后，ASD儿童在三项抑制性任务中的两项上表现出受损。结果表明，自闭症儿童的经验，在某些方面，但不是所有的抑制控制有限的赤字。更一般地说，研究结果强调了使用多种措施来评估一个假定的单一认知能力的重要性。
Impairments in executive abilities such as cognitive flexibility have been identified in individuals with autism spectrum disorder (ASD). It remains unclear, however, whether such individuals also experience impairments in another executive ability: inhibitory control. In the present study, we administered three inhibitory tasks to 18 children with ASD, 23 siblings of children with ASD, and 25 typically developing children. After controlling for individual differences in age, overall IQ, and processing speed, children with ASD demonstrated impaired performance on two of the three inhibitory tasks. Results suggest that children with ASD experience circumscribed deficits in some but not all aspects of inhibitory control. More generally, the findings underscore the importance of using multiple measures to assess a putative single cognitive ability.
